SASH-OPERATING DEVICE.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed March 19, 1908. Serial No. 422,109.

To all whom it may concern:

Be it known that 1, Louis BARBIERI, a citizen of the United States, residin at New York, in the county of New York and State of New York, have invented certain new and useful Im rovements in Sash-Operating Devices; anc I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to car construction and particularly to the construction and operation of car windows. While it is neces sary that these car windows be permanently fixed when raised in order to avoid vertical movement, by reason of excessive jars, it is also necessary that they be easily operated, and held in different positions in the frame. Many devices have been constructed to accom lish this function, but none of them have Ewen free from several seemingly inherent difliculties, and it is not known that an automatically raised window has ever been made to throw itself into locked posi tion when in its extreme u )per position, t. 6., when the window is closed.

It is the object of this invention to avoid the difficulties of previous inventions, and to accomplish the features recited before in an efficient manner.

In the drawings, Figure 1 is a transverse elevation with parts in section; Fig. 2 is a vertical sectional view taken on line 22 of Fig. 1 Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1. Fig. 4 is a detail vertical section taken on line 44 of Fig. 1 and Fig. 5 is a fra 'mentary view of the sill piece and associated parts.

Referring more especially to the drawings, 1 represents the frame work of the window which is provided intermediate its length with a sill piece, 2, upon which the inclined sill plate 3 is mounted, having at its inner edge as usual the upstanding flange 4. Sliding between the guide beads 5 and 6 is the usual frame 7 grooved in the lower edge of the lower rail, as at 8 to receive the flange 4, and having depending from its lower edge a air of arms 9, which are extended forwarc y at their lower ends, as at 10, and provided with an inwardly turned lug for the reception of the operatingcords 11.

The operating cords 11 extend from their connection with the lugs on the depending arms 9, over pulleys 12 secured to the sill piece 2 and downwardly between the sides of the frame, to pulleys, 13 and 14, secured respectively upon the top and bottom side of the base piece 15, whence they are lead to opposite sides of the winding drum 16, journaled upon the base piece 15 in position to be acted upon by the pawl 17. This pawl is normally held in engagement with the teeth of the periphery of the drum 16 by the leaf spring 18, which engages the rearward extension 19 of the pawl, normally forcing it up against the weight of the operating shaft 20. This operating shaft is pivoted or otherwise engaged with the rear end 19 of the awl and extends upwardly through the sire piece of the frame to a point approximately level with the bottom part of the frame, where it is connected with the thumb piece 21 slidably mounted within a slot 22, formed in the side piece.

In order to lower the window it is first raised to free the grooved edge 8 from the flange 4, and then depressed against the action of the spring drum 16, the pawl 17 holding it in any adjusted position. Upon releasing the pawl by the action of the thumb piece 21 upon the rear end thereof, the spring drum operates to draw the cords over the pulleys 12, and thus raise the frame to a position where its lower grooved edge 8 is raised above the flange 4. The position of the pulleys 12 is such that when the arms are adjacent thereto the tendency is to pull the arms toward the pulleys thus throwing the sash over the flange 4, and allowing it to drop by gravity until it is engaged with the flange so as to lock the window in raised position. To explain this action it may be stated that the spring while having insufficient strength to raise the sash to the upper part of the frame is strong enough to throw it to this position when the sash is started from its lowermost position under the tension of the spring drum. The sash would probably rise to a point within an inch or so of the top of the frame under ordinary conditions, but before the force of gravity overcomes the movement of the sash it has passed its limit of u ward movement and, therefore, when puffed over the flange 4 drops back into position in locked engagement therewith.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Having thus described my invention what I claim as new is l A window comprising in combination, a sill piece, a sash and means to raise the sash which forces the same into a position over the sill piece.

2. A window comprising in combination, a sill piece, a locking flange thereon, a sash and means to raise the sash which forces the same over the flange.

3 A window sash arrangement comprising the combination with a sill piece, of a sash constructed for locking engagement wlth such slll piece and means for automatically raising said sash tending to force it laterally so that on the descent thereof it shall enter into looking engagement with said sill piece.

4. In a window, the combination with a sill piece, of a flange thereon, a sash, raising arms thereon, and means connected to said raising arms to raise the sash tending to force the sash laterally over the sill piece.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LOUIS BARBIERI.
